Longest Life Batteries for Solar : Trojan T105 RE 6 Volt



Specifications: Model: T105-RE Voltage: 6V 20 Hour Rate: 225Ah 100 Hour Rate: 250Ah Weight: 67lbs Length: 10.375in.
Width: 7.125in.
Height: 10.875in.
Country of Manufacture: U.S.A.  Flooded lead-acid batteries have the longest track record in solar electric use and are still used in the majority of stand-alone alternative energy systems.
They have the longest life and the least cost per amp-hour of any of the choices. However the other side of the coin is, in order to enjoy these advantages, they require regular maintenance in the form of watering, equalizing charges and keeping the top and terminals clean.
Some examples of flooded lead-acid batteries used in solar and wind electric systems are 6 volt golf-cart batteries, 6 volt T105's and 2 volt industrial cells for large systems. Specially designed deep-cycle cells are much less susceptible to degradation due to cycling and are required for applications where the batteries are regularly discharged, such as photovoltaic systems, electric vehicles (forklift, golf cart, electric cars and other) and uninterruptible power supplies. These batteries have thicker plates that can deliver less peak current, but can withstand frequent discharging. Trojan Battery Company is the world leader in deep cycle battery technology. Since 1925, Trojan has been a pioneer in the development of superior deep cycle batteries..... 
_________________________________________________________________________


Trojan batteries have been used in standalone power systems in remote cabins for the past 25 years with great success. Because of their low initial cost, they are the most affordable true, deep cycle batteries. The T105 golf cart battery is designed to be used in small electric vehicles where they are cycled heavily and last about 2 years. In a remote home system where they are cycled down 20% every day they can last 3 to 6 years. Trojan’s Renewable Energy (RE) Series is a line of technologically advanced lead-acid deep cycle batteries, optimized for renewable energy applications such as solar PV, small wind, and micro hydro. They have heavier duty separators and plates designed for longer life and their warranty has been extended to two years free replacement and 60 months additional pro-rated on the L16s and 36 months pro-rated on the T-105.
This series of deep cycle, lead-acid batteries from Trojan are optimized for micro-grid, solar, small wind, and other renewable energy uses. Designed for extended lifespan, the Premium line has a full two-year warranty, and a prorated for up to five years.

Trojan Premium line of batteries are made with a 10-year battery life in mind. They feature Alpha Plus Paste with T2 Technology, which considerably improves the porosity of the active material resulting in improved performance over longer periods of time; combined with Trojan’s DuraGrid design it increased the overall life cycle of the battery.

The case of of all the Trojan Premium batteries use their branded Polyon container which is a rugged protection against difficult environments and prevents potential acid leaks.

Providing increased lifespan, Trojan’s Smart Carbon technology is now featured in both the Premium and Industrial lines, improving partial state of charge (PSOC) performance and longevity alike. The specially designed formula of Smart Carbon enhances charge acceptance and efficiency by increasing the electrochemically active surface area of the battery. This is particularly beneficial (and efficient) when batteries are not regularly charged to full capacity.

Small scale Solar panels to power all your stuff.

I hear everyday that the reason people are not installing Solar Panels is because they are so expensive. And this is True.

I had a quote to provide 500 Kwhr/mo Solar Power (grid-tied)  to my house and the cost was $23,000 .... Add another $10,000 for batteries and you are easily up to $33,000.

Most people use 1000 KWhr per month of Electricity so you would need to double that cost to $66,000.  Yes, I agree this is very expensive.  Until they come up with a better Solar Technology most of us will never ever be able to afford Solar Power.

Unless.... unless you take a really good look at your consumption and see if you can reduce it to 300 KWhr / mo .... 10 kWh per day.  Or better yet reduce it to 100 KWhr per months. Is this possible in Canada or in very hot or cold climates ?

If you live in an area that has on average 5 hours of sunshine, with a 280 watt Solar Panel you can be making roughly 250 * 5 =  1,250 watt per day...  1.25 kwhr / day. That works out to 37.5 KWhr/mo .... Can you get your consumption down that low ?  Yes you need to have additional Solar panels and batteries for cloudy days and certain inefficiencies but you see it is possible if you reduce the amount of Electricity you are using.

The way I am approaching this is learning how much each appliance requires to run each day and for how long. When I go completely off the grid I will need a small solar fridge, propane cooking stove, BBQ, about 10 LED lights and battery to power my computer and other devices. Heat will need to be via a Wood stove. I am looking for an old Amish Cook Stove that can also help to heat a very small, well insulated Offgrid House I will build.

In order to learn this I am starting with Small Solar panels and learning what I can charge with each one. So far I am able to charge several LED lights, my computer, a fan, phone, and iPod.

I am now searching for the most efficient Solar powered Fridge I can afford.

What do I need to live off the Grid ?

It depends on where you live. It is one thing to live off the grid in Costa Rica, it is quite another to live off the Grid in Northern Canada. The Technology is constantly changing, constantly improving.

The Basics are shelter from the elements, clean drinking water, food and power ....

We will cover each Topic in the coming days but starting with Power you will need to know how much energy you currently use and how much energy you will need to operate the critical appliances you use on a  daily basis. Lights, Fridge, Heating, computer  etc.....


Take a look at your current Hydro / Electricity Bill. Do you use 500 KWhr per month ? More ? Less ?  You will need to learn how to use less.


There are many sources for off-grid Power, but as you can see form the running poll on the right the best value is Solar. You need to know how many hours of sunlight you get each day? 5 hours ? More / less?  If you can capture 5 hours of sunlight each day, with a 280 Watt Solar panel you should be able to generate about 1,000 watt hours per day. - 1 KW hr....  so 30 KWhrs per month.  If you are using 500 kwhr per month  you would need 500/30 of these panels. 


So 17 - 280 watt Solar Panels + Controllers, Inverters and Batteries.


But you would also need a gas generator Back-up Power for the days where there is no sunshine.

We found this 400 Watt Kit that includes Solar Panels,Controllers, Inverter for $805 (Does not include 12 Volt battery) ....
WindyNation Complete 400 Watt Solar Panel Kit with 1500 Watt VertaMax Power Inverter RV, Boat, for Off-Grid 12 Volt Battery :

  • Solar charging will provide on average 1600 Watt Hours (Wh) or 135 Amp hours of charge per day (depends on sunlight availability)
  • Designed for RVs, cabins, homes, boats, back-up and remote power use
  • Bundle and save! Purchase all the components together and save time and money!
  • Perfect kit for a off-grid 12 volt battery system. 1500 Watt VertaMax Inverter provides plenty of AC power to run your household appliances !


  • The best part about this kit is that it shows you in one diagram all the parts and pieces you will need to actually run something using Solar Power (except the 12 Volt battery) . Before you can decide what to buy though you really need to understand what you will be using Off the Grid.  A Computer ? 10 LED Lights ? a small fridge ?  (To be continued)
